SPATIAL POWER COMBINING OSCILLATORS BASED ON AN EXTENDED RESONANCE TECHNIQUE

Several spatial power combining oscillators employing an extended reso nance technique have been designed and fabricated for the first time o n single layer microstrip structures, Power combining efficiency, circ uit tolerance to individual device variations and the effect of device failures on circuit performance mere studied, Results obtained indica te exceptional circuit tolerance to individual device parameter variat ions as well as to device failures, The combiners described herein wer e designed and operated at 8 GHz with effective radiated powers of 0.2 2 W, 0.64 W and 4.3 W for a two, four and a nine device combiner, resp ectively.
